If only this was not a Monday and the first work day of the “dark season.” The few minutes I was able to spend outside were pretty fantastic! Highs this afternoon have reached the mid-60s most spots, even nudging on the upper 60s downtown for a little bit. We’ve got a near copy tomorrow with temperatures likely even a smidge higher.

Through Tonight: Thanks to those light winds and clear skies, we’ll see temperatures plummet about as quickly as they rose today. More temperature spreads around 30-degrees from day to night seem like a good bet in spots. Lows reach the low-to-mid 30s in the coldest outlying areas to near 40 or the low 40s downtown. Watch out for some late-night patchy fog throughout the area and spots of frost in the coldest locales.

Tomorrow (Tuesday): There may be a bit of fog around in the morning, but it should burn off fast. Mostly sunny skies help temperatures shoot up toward highs ranging from the upper 60s to near 70. I’m definitely considering catching a cold this evening and having a sick day tomorrow...

Sean forming? A low well off the Southeast Coast (~400 miles southwest of Bermuda) continues to show signs of organizing. It’s non-tropical, but it has a large wind field with gale force winds extending several hundred miles to the north of the center. The National Hurricane Center gives it a 60% chance of developing into a subtropical system, which would take on the name Sean. As of now, an incoming cold front late week looks to keep this system offshore.
